How to connect non IP devices into the UPnP™v1 fabric Vijay Dhingra Director of Standards Echelon Corp.

Enhanced Consumer’s Experience To enhance consumer’s experience with home automation, “all devices” in the home need to integrate seamlessly with computer and A/V network. Examples of “all devices”  Of course, computers, printers, PDAs, Cell Phones, A/Vs  And non-IP devices – light switches, thermostats, occupancy sensors, security sensors, etc.

Seamless Integration? What is seamless integration for consumers  Zero-configuration, "invisible" networking, and automatic discovery  A breadth of device categories from a wide range of vendors.  Dynamically join a network, obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other devices  Same experience with UPnP devices and non-IP devices

Interaction bridge & UPnP devices Interoperable open standard ANSI/CEA UPnP

Why do you need a Bridge Prohibitively expensive to implement UPnP stack in “everyday devices” such as light switches, thermostats etc. Ability to connect with largely deployed legacy networks. Connects UPnP devices and control points with non IP devices

Requirements for Non IP device Fabric True Open System  Standards-based interoperable technology  Multiple subsystems, multiple product vendors, multiple integrators, multiple user interfaces, multiple markets. Interoperable  Freedom to choose best of breed products from multiple vendors and have them work together.  Ability to enhance home over time without being locked into a single vendor or support contractor.

Requirements for Non IP device Fabric (Cont) Scalability  Number of devices per network, flexibility of deciding media types, mixing and matching of different mediums.  Power Line, twisted pair, fiber optic, RF, etc  Distributed control systems with peer-to- peer communications (direct communications among transducers without mediation by a master). Cost Savings  Lower product cost, installation costs, life- cycle costs.

Requirements for Non IP device Fabric (Cont) Built-in Security  Low overhead built-in security. Time to Market  Faster implementation of newly developed and fully optimized End-to-End solution products and tools.

Pervasive Network Statistics LonWo R ks® technology from Echelon is the most widely used network in the world for home & building automation  Over 30 million LonWorks devices installed worldwide  Wide range of LonWorks products available from thousands of manufacturers LonMark® Interoperability Associations  Industry groups define how products work together  Certification program has approved ~ 500 devices & certification centers located worldwide.

Solution - Architecture LONWORKS® Networks LNS® Network Operating System UPnP ™ Protocol

Solution implementation LonWorks technology semantics – LonMark® functional object and network variables are defined at the application level (similar to UPnP™ functional profiles) LonMark® objects are mapped into UPnP™ devices

Solution implementation details On any PC – bridge application with Echelon’s LNS® (LonWorks Network Services API) loaded in a server- independent mode  All the mandatory network variables are mapped into UPnP™ stack  Optional features (manufacturer’s specific extensions) can further be developed in the future Translator modules as Microsoft.Net™ assembly DLLs.

Software Architecture of LonWorks/ UPnP Bridge

Hardware adapters Possible solutions:  PL to Serial converter  PL to Ethernet adapter  i.Lon 10  PL to Web Services Server  i.Lon 100  PL to PCI Bus  PCLTA 20 – SMX w/PLM 22

Conclusions With existing technology, everyday devices (LonWorks devices) can successfully be mapped into UPnP domain. Further work is required to commercialize the hardware and software bridge.
